Answer:
$4000
Explanation:
Fractional banking is a banking system where a portion of customer's deposits is kept as reserves while remaining portion is lent out. The amount kept as reserves is determined by the required reserve ratio set by the Central bank.
Reserve ratio is the percentage of deposits that is required of commercial banks to keep as reserves
Total deposits = $100,000 + $5,000 = $105,000
Required reserves = 0.2 x 105000 = 21,000
total reserves = $20,000 + 5000 = 25,000
excess reserves = 25,000 - 21,000 = 4000
